Koni threaded spring perch sleeve kits allow vehicles that would normally have fixed location spring perches to gain some of the benefits of racing-developed tuning techniques. Performance suspension adjustments such as ride height and corner weighting or weight jacking can be performed with threaded spring perches and individual components. Koni offers several coil-over threaded spring perch sleeve kits to allow both street and race cars these performance benefits. These threaded sleeves are made of anodized aluminum and are specially designed for load-carrying and self-cleaning properties. All lower perches have a nylon-tipped locking set screw to positively lock the perch in place without damaging the threads.
